Any options for rounding the ends of the curves

Something that is often missing is the ability to round the ends of curves, this can be achieved by converting the curve to mesh and making a bevel... but it loses all the benefits of being a curve.

I propose an option to be able to round these in the bevel>round section and below fill caps, to have the 2 options available the close flat and the close rounded.

And as an extra also for geometry nodes
